Bacillus thuringiensis (Bt) is currently the most widely used microbial insecticide. Its main insecticidal component is the toxin protein in the parasporal crystal. Among them, the relative molecular weight of the toxin protein toxic to lepidopteran pests detected in this standard is 130kDa. In the bioassay, night-dried beetroot is used to detect the toxicity of Bacillus thuringiensis powder with characteristics against the lepidopteran insects of the genus Spodoptera, and diamondback moth and cotton bollworm are used to detect the toxicity of Bacillus thuringiensis powder with activity against Bacillus thuringiensis lepidopteran insects. This standard is formulated based on the relevant materials of the Bacillus thuringiensis industry and industry standards previously formulated in my country, and in accordance with the actual situation in my country.
This standard makes specific requirements and provisions on the requirements, test methods, sampling, packaging, transportation, etc. of Bacillus thuringiensis powder, thereby providing a unified technical basis for the production of Bacillus thuringiensis. Appendix A of this standard is an informative appendix. Appendix B is a normative appendix. This standard is proposed by the Ministry of Agriculture of the People's Republic of China. Drafting units of this standard: Pesticide Control Institute of the Ministry of Agriculture, National Engineering Research Center for Microbial Pesticides of Huazhong Agricultural University, and Chaobei Province Biological Pesticide Engineering Research Center.
The main drafters of this standard are Jiang Hui, Yu Ziniu, Chen Shouwen, Zhu Kaimei, Gong Xiaojun, Hao Xinping, and Gu Baogen. The Ministry of Agriculture's Institute of Drug Control is responsible for interpreting this standard. Scope
